furnished in front with corresponding registering bevel are fan-lips, of which the upper ones 28 are stationary and the lower ones 29 are adjustable to open and close or partially 5 close the mouths 30, as the case may be. The

upper jaws 26 are also provided with overhung rear lips 31, that hang pendent over the lips of the lower jaws 27 at the sides of the jaws back of the fan-lips of the mouth. The said overhung side lips shut off the discharge of water from the sides of the jaws back of the fan-lips, while at the same time they allow the upper and lower jaws to be disconnected clear back to their integral attachment-fianges, respectively, 32 and 33. The said attachment-flanges, and with them the jaws, are firmly secured to the front plate of the sluice-gate frames by the bolts 34, that are seated in the perforations 35 in said flanges, and in said front, intermediate, and rear plates of the frame, and there are-secu red by the screw-nuts 36. T

87 represents the actuating slide valve stems, which stems are seated and work within the recesses 38, formed by the single central corrugations of the rear sluice-frame plates 19, and which stems are fastsecured to the valves 23 that they operate. A fast bevel collar or swell 39 projects from said stem at just the height above said valve to help stay its downward drop when the valve is at closed port, at which time said bevel swell-collar rests in its bevel recessed seats 40, which are sunk into the upper edges of the rear and intermediate plates of the sluiceway-frames.

41 represents spiral push-springs that are mounted on said actuatin -stemsand push against said swell-collars at their lower ends and against the perforate buffer-washers 42, that are seated against the under side of the The said springs hold the slide-valves in their normal closed-port position.

Perforations 44: through the side bars of the platform-frames on line with the actuatingstems of the slide-valves provide free working scope for said stems and for the linkhooks 45, that engage in the perforate heads 46 of the stems and in the perforate lower arms 47 of the bell-crank levers 48, which bellcranks have loose bearings on the journalshaft 49, onwhich they are steadied by the washer 50, and which journal-shaft has boxbearings 51, secured on the skids that support the barrel-tank, and said journal-shaft reaches from side to side of the platform and journals both bell-cranks that on their respective sides of the platform operate the slide-valves that regulate the supply of water to their respective nozzles. The upper perforate arms 52 of the bell-crank levers are engaged by the lower hooks of the long actuating-rods 53, whose upper hooks engage in their center bearings 54: in the treadle-bars 55, which treadles are journal-mounted on the pivot-bolts 56, which bolts are secured in the foot platform-frames 8, and said treadles are steadied on said pivot-bolts by the washers 57. Foot-boards 58, secured to the tops of the treadles,present footholds for the driver, by pressing against which with his feet, respectively,inagainst the treadles on either or both sides of said platform he is enabled to lift the slide-valves on either or both sides of the sprinkler and hold them liftedas long as his feet rest against the treadles, so as to provide a free flow of water to and through either one or both of the nozzles.

represents draw-screws of a special construction for the adjusted contraction and expansion of the months 30 of the fan-nozzles 'let. 1 preferably use, as I have shown, three of said screws, one to the middle of the fanshaped lips and the other two to the corners; but I do not confine myself to any special number. The said drawscrews and their several parts being of like construction are alike numbered and described. The said draw-screws are formed with screw-threaded lower ends (51, enlarged top portions 62, having bevel swell-collars 63 at the lower ends of said enlarged portions, and screw-threaded upper terminals 64:. The upper ends ofsaid screws are seated within the flange-sockets 65 in the roof of thernouths or upper lips and jaw of said nozzles before the attachment of the jaws to the sluice-gate frames, the bevel swell (53 in each case at the foot of the enlargement 62 of the screw fitting into the bevel entrance 66 from the roof of the mouth of the nozzle into the flange-socket 65. After the top of said draw-screw in each case has been so seated, as above stated, the screwhead 67 is screwed home on the screw-threaded upper end of said screw that projects above the flange-socket until said attachment screwhead rests on the upper edge of the flangesocket 65. The upper end of the threaded screw within the attached head is then slightly riveted, so as to re-enforce its hold on its screw-head. A slot (58 is then cut transversely across said screw head, passing through both the screw-head and the upper end of the integral screw that said attachment end caps. The lower jaw of the nozzle is next coupled to the upper jaw by the insertion of the lower screw ends of the three draw -screws in the perforated screws (39, which are formed, respectively, within each of the swells 70, beneath the lower jaw. The screw-coupled jaws can then be secured to the front-plate 21 of the sluice-gate frame, as described, by the screw-bolts 34.

71 represents vertical major screw-driver shafts, which have their lower journal-bearings 72 within the integraljournal-box tubes 73 on the center projections of the horizontal arc bearer-brackets 74, the perforate attachment-fianges75 of which brackets are secured to the front plate 21 of the sluice-gate frame by the screw-bolt '76. The upper end of said screw-driver shafts have their jour- IIO Izo

nal-bearings 77 in the journal-boxes 78, Whose perforate flanges 79 are secured to the'rear end of the platform 3 by the screw-bolts S0.

81 represents intermediate journal bearerbrackets whose perforate flanges 82 are se cured to the front plate of' the sluice-gate frame by the screw-bolts 83. These upwardly and forwardly projecting bearer-brackets are provided at their upper forward ends with integral tube-box swells 84, that provide the intermediate journal-bearings S for the middle of said vertical major screw-driver shaft box tubes 73, in which said shaft has its may be rigidly secured to their seat on said lower j ournal-bearings. The said gear-wheels driver-shaft by the screw collars ornnts 89, that are screw-seated on the threaded peripheries 90 on said driver-shafts on each side of said gear-wheels.

v 91 represents-the driver lugs or tenons of said major driver-shafts, which lugs engage in the slots 68 of the draw-screws 60 to effect 95 are the follower screw nuts or caps that,

are screw-seated on the upper screw ends 96 of said minor screw-driver shafts, whose lower ends are provided with the tenons or lugs 97,

that engage in the slots 68 of the draw-screws beneath them.

98 represents side gear-Wheels, which are fast mounted on said minorscrew-driver shafts in registering line and havinggeared engagement with the center gear-wheels that are mounted on the major screw-driver shafts 71. The said side gear-wheels are fast secured to the minor driver-shafts that carry them in close proximity beneath the journaled boxtubes 92, as in the center gear-wheel to its major driver-shaft beneath its j ournal-box tube 7 3 by means of follower screw collars or nuts 99, which engage on their screw-threaded seats 100 around said minor screw-driver shafts 02. It will thus be seen that when said major screw-driver shafts are turned and turn their underlying screws either to expand or contract the jaws and lips of the fan-nozzles the center gear-Wheels mounted on said major drive-shafts as they mesh into the side gear-wheels thereby command and turn the minor screw-driver shafts and the screws that they surmount, so as to simultaneously work on the corners of the mouth or lips as their forward coadjutary ,screws operate on the middle of said mouth to simultaneously reguing -'chain,

late the expansion and contraction of all parts of the mouth of said nozzle.

1 have shown in the vertical section, Fig. IV, the center draw or expansion and contraction screw.60 with a left-hand thread and the side screw, also 60, having the same gen eral construction, located at the corners of the mouth with a right-hand thread, for itis evident that as the center gear-wheel on the majorscrew-driver shaft turns the side gearwheels that are mounted on the minor screwdriver shafts that said side gear-wheels and the shafts on which they are mounted must So of a necessity rotate simultaneously in a reverse direction to the gear that drives them,

and consequently the actuating-screws that they drive must simultaneously move in op-.

-neous purpose. I

101 represents sprocket-wheels that are fast mounted on the summit of the major screwdriver shafts, and 102 are the sprocket-teeth in the 'peripheryof said wheel.

103 represents stretches of gearing-chain .posite direction to effect the same simulta.-.

that engage with the sprocket-teeth of said wheel, and 104 are long-linked duplex connecting-rods,whose rear hooks 105 on each of the corresponding rods engage, respectively, in the terminallinks of said stretch of gear- The said duplex rods 104 are seated and work in the-staples or slotted lugs 106, which latter are secured in theside pieces of the platform-frame 3. The forward hooks 107 on said duplex rods engage, respect: ively, in the terminal links of the forwardstretch of gearing-chain 108, the links of which latter chain engage with the sprocketteeth 109 of the sprocket-wheel 110, which. sprocket-wheel is fast mounted on thevertical operating-rod 111, the foot 112 of which rod works in the journal-box 113, which journal-box is secured to the platform 3 by the screw-bolts 114:. The upper end of said operating-rods are seated and work in the perforate journal-lugs 115, the connecting-strap of which perforate j ournal-lugs is secured to the bottom of the drivers seat, and the said jour- 116 represents hand-cranks that are fast mounted on the tops ofthe operating-rods, and the handles 117, by which said cranks are turned, are thus convenient tothe drivers hands, on each side of his seat, for the adjustment of the volume of the discharge from the mouths of the nozzles on either or both sides ofthe sprinkler. The flooding or sprinkling devices described above are duplicated on each side of the sprinkler. V

The operation of the invention'is as fol-' lows: It is to be understood that the normal position of the slide or drop valves 23,,that command-the sluice-gateways, is dropped to closed port, which position they attain and retain by the force of the push-springs il and by their own gravity, so as to prevent the flow of water except when the ports are opened by the action of the driver. When the driver presses against and pushes the treadle or treadles on each or both sides of his foot-platform in accordance with whether it is re quired to sprinkle from the one nozzle or both, then by means of the rods 53'and the bell-crank 48 the sliding valve or valves, as the case may be, are elevated on respectively one or both sides of the sprinkler and the flow of water tothe fan nozzle or nozzles is in full force, and it can again be instantaneously shut off at any time when passing over a footcrossing by lifting the drivers foot from the treadlc or treadles, the flow being immediately again effected by forcing forward the tread'les.

In finishing up the sprinkling of a street there is sometimes a narrow strip that requires only the work of one nozzle to effect the sprinkling of the residue, in'which case the driver lifts his foot from one of the treadles, and the valve in that side immediately closes. Now in some seasons of the year and insome conditions of the weath'erit is required to sprinkle more heavily than at other times. To effect this change and either to expand or contract, as the case may be, the mouths of the fannozzles, the driver by simply turning the crank-handles on each side of his seat turns the operating-rods 111, the sprocket-wheels 110 at their feet, which drives the endless combines of gear-chains and link-rods, the sprocket-wheels 101, the major and minor screw-driver shafts, the gear-wheels on said drivershafts that, meshing together, make said shafts co operative, and, lastly, the adjusting draw and withdrawal screws 60, which, as they are thus turned by the action of said hand-cranks, as'previously described, either expand or contract the mouths of the fan-nozzles, respectively, as the case may be, according to whether the hand-cranks are turned to one side or the other. It is almost always, if not invariably, desirable to sprinkle heavier toward the summit of the street than toward its side gutters, for the self-evident fact that the sprinkled water tends to run from said summit toward said gutters. Now by means of the adjustable expanding and contracting lips of my fannozzles the driver is enabled without stopping or leaving his seat to adjust and readjust the opening of the mouths of the fan-nozzles on either side of the sprinkler independent of each other, so as to change at will the respective flow through the individual nozzles. The mouths of the nozzles can by the above specified expanding and contracting device be set, and each of said nozzles irrespective of the other be setto a full flow or to the lightest sprinkle or to any intermediate increased or decreased flow, and the lips will remain in the exact adjustment to which they have been screwed by the driver-shafts under the operation of the hand-cranks. The driver,

as soon as he has adjusted the opening of the mouths of said nozzles, can remove his hands from the hand-cranks by his seat, and he does not need to pay any further attention thereto until from any cause it is desired to abate or increase the flow from either nozzle.

The above-described means for the expansion and contraction of the lips of the fannozzles provides the means for the adjusting and readjusting the flow to suit the various conditions of the streets and formation of the road-bed,so that as the sprinkler passes over a granite, concrete, wood, or gravel road-bed, and from one to the other, requiring, respectively, either a light or heavy sprinkle, the lips of my fan-nozzles are easily adjusted without the stopping of the sprinkler and retain their adjustment. It will also be seen that the flow of water from the tank to the mouth of the fan-nozzle has no sudden buffer-stay on its way to the objective. point of its discharge. The curved foot of the discharge-tubes switches the water around into the nozzle without much frictional loss, while the peculiar shape of the two jaws of the fan-nozzle, which incline, respectively, toward their meeting line from below and above, concentrates the force of the discharge toward that line that effects the carriage of the water-fan to a greater distance than could otherwise be accomplished.
